Title: Factors Influencing Concrete Repair

Abstract:Two very important factors influence the selection of a specific material for a repair program: relative volume change and preparation of the repair inter-face. Differential volume changes between the repair material and concrete imposes stresses at the interface between the repair and the concrete which may cause cracking in both the sound concrete and the repair material. The most direct method recommended to minimize differential initial shrinkage is to minimize the water content in the replacement concrete.
